In America, 240 million people are the Internet. And in Russia, 60 million people are online. That's nearly half of Russia's population of 142,946,800. Russia is currently the largest Internet market in Europe, and its Internet population has been steadily growing year over year. The population of Internet users has just hit 42.8% of the entire Russian population. Last year, we wrote about the top 10 startups of 2011. But what are the top Russian startups? And are they all just American knockoffs?

We took a look at Russian startups, breaking them down into five categories: hotel booking, games, daily deals sites, discovery engines and social networks. Here they are, in no particular order whatsoever. The Russian Version of Kayak and Travelocity is a Russian hotel booking site similar to the American sites Kayak and Travelocity. It received $5 million in April 2011. The site's founders are also behind online property and DataArt, a premier software developing site for the EU and USA travel sectors. connects with users' profiles, and aggregates reviews from CEO Marina Kolesnik, who is from St. Petersburg, studied at Harvard Business School. Quintura calls her one of the "most visionary female internet entrepreneurs in Russia."

ZeptoLab Is Russia's Answer To The Super Popular Game Angry Birds

What's better than throwing angry birds at stone-and-wood structures populated with green pigs? In 2010, Moscow-based Russian developers Zeptolab created the iOS game Cut The Rope. Published by Chillingo, the game has already reached 60 million downloads. "Cut the Rope" is essentially a physics game that feels a lot like "Angry Birds" in terms of how it's played. Users use a finger to cut the rope at an angle. A piece of candy falls, hitting stars on its way down. Sometimes the piece of candy hangs by three ropes; other times by one. Zeptolab has not received any venture money for this, and by August of last year, ZeptoLab released a sequel, Cut The Rope: Experiments.

BigLion Is Russia's Answer To Groupon, And A Total Rip-Off

BigLion delivers "the highest revenue growth in Russia's Internet history," according to Quintura. This site does, however, look and feel exactly like Groupon. TechCrunch wrote about Big Lion in April 2010, noting both how ideologically close it is and shooting down its very "cut/copy" ideas. "But how anyone can hold their head up high when this is hew they make a living is beyond me," writes TechCrunch's Michael Arrington. Ouch. Something must be working, however, because BigLion is making $15 million monthly revenues over its short 1.5 year run. At the end of 2011, Russian business daily Vedomosti reported that BigLion attracted funds from Tiger Global Management. East-West Digital News reported that BigLion co-founder Oleg Savtsov confirmed the deal; Vedomosti learned that the investment volume was in the $25-$30 million range. Here's a screengrab of what it looked like in 2010. The site has since been updated to appear less Groupon-like.
